3.3 Electric installation
3.3.1 Grounding
(1) Grounding: All module frames should be grounded for safety. It is
not recommended to use modules with different configurations
(grounding, wiring) in the same system. The combination of the material
of frame and the material of grounding would not result in galvanic
corrosion.
(4) All module frames should be grounded for safety. The
grounding connections between modules must be approved by a
qualified electrician, the grounding itself must be made by a qualified
electrician. The ground wire should be at least the same size as the
electrical conductors.
(5)In order to avoid the damage caused by PID, BYD suggests
that the negative of inverter should be grounded.
(6) The grounding system must be installed well.

4. Maintenance and Care
Rev. Aug. 24th 2012
CAUTION: If the system goes wrong, please let the
professional engineers deal with it. Others should not
disassemble the system optionally.
4.1General
The inspection should confirm the following:
(1) Check the module’s setting of machine on time. Check the
support equipment (fastness, erosion, bolts and nuts, especially the
place where the wind or shake is hard. Ensure the fixing is fast. If not
fast, screw them down.) If the condition permits, the metal fittings that
fasten or support the modules should be protected from the eroded,
such as the bolts and nuts. A first check after 12 months and an
additional check after 120 months should be made.
(2)Check the module’s electric line (connection to the equipment
and earth) for a settled time. Check the grounded resistance satisfying
the designation request. If the connection is not fast, jointing it. After the
thunderstorm or before, check the junction box and other protectors for
the thunder. If invalidation, replace it according to the request.
(3)Check the lead connector for the leakage current and deal with
it. Be care for the rainy or snowy weather which affects the leakage
current. When checking the lead, People must take the insulated sets
(such as tools and gloves). Don’t touch the uncovered lead or the
connectors with uncovered hands. Check the connections of each part
to ensure them fast, if not, connect them. Wipe the dust up from the
equipment regularly to keep it clean.
(4) If the module needs repaired, covered with fabric or other
material. Or it may produce high voltage under the sun.
4.2 Module Cleaning
Over dirt and dust can accumulate on the glass surface of the
module, reducing its power output.BYD recommends periodic cleaning
of PV modules to ensure maximum power output especially when the
modules do not have the expected power output. Check the glass to
ensure the surface is good before cleaning. If it is broken, please do not
clean and inform to the purchaser and maintenance. Do not wear the
watch or jewellery when cleaning. Use the soft fabric clean out the dust.
If the dust is hard to wipe out, use the water to clean. Then use the
clean fabric wiping up the water carefully. Do not use hard tools or
mordant solution wiping the module for avoiding leaving scrape so as to
affect the light transmission efficiency. The power attenuation caused
by the scrape is beyond our guarantee range. Do not wipe on the day,
and you had better to clean on the night or morning without strong
sunshine. Do not use the cold water to clean the module so as to
avoiding broking the glass.
